345 Quincy Street, Brooklyn

Unpermitted cellar alterations, front door lock violations, and off-season heat calls flag this Bed-Stuy three-family townhouse.

A 1931 Bedford-Stuyvesant three-family townhouse where unpermitted cellar plumbing and layout alterations sit alongside active building-wide heat complaints. Three things to know:

Code citations cover unpermitted internal stairs, key-lock entrance doors, and illegal cellar plumbing. The house carries open code violations for an unapproved key-operated double cylinder lock at the entrance, unpermitted staircase alterations piercing the floor, and illegal cellar living quarters with unapproved plumbing fixtures.

Air quality complaints on surrounding blocks point to potential ventilation and riser bleed issues. Within three blocks of the house, 14 air-quality complaints were filed last year covering indoor odors and fumes. In small multi-family structures, ventilation and riser pathways can bleed exhaust into residential living spaces.

Quieter signals on this building and the blocks around it:

• Two building-wide heat and hot water calls were logged in June 2026 alongside earlier mold and leak reports.
• 328 residential noise complaints occurred within three blocks last year, heavily dominated by loud music and parties.
• An LLC acquired the property in July 2021 following long-term private ownership.
